Tag management in a tag cloud

ABSTRACT

A method for managing tags in a tag cloud may include receiving a tag for an object and comparing the tag to existing tags for the object. The comparing may include determining if there is a relationship between the tag and any of the existing tags. The method may also include adding the tag to the tag cloud in response to there being no relationship between the tag and any of the existing tags. The method may additionally include selecting one tag of the existing tags in response to the tag and the one tag being related tags. The method may further include presenting the related tags in the tag cloud. Presenting the related tags in the tag cloud may include at least one of modifying the one tag in the tag cloud, indicating the tags are related, and combining the related tags into a single tag.

BACKGROUND

Aspects of the present invention relate to tag clouds, and more particularly to a method, system and computer program product for managing tags in a tag cloud.

Tag clouds have become a common collaborative instrument to capture metadata about an object, such as for example, a news article, webpage, multimedia presentation or similar items. A tag cloud is a visual representation for text data. A tag cloud may be a visually representation of user-generated tags. Tag clouds may be used to describe the content of a website. The tags are usually single words and are normally listed alphabetically. An importance of the tag or popularity may be illustrated by a font size of the tag and/or color of the tag. This formatting is useful for quickly perceiving the most prominent terms and for locating a term to determine its relative prominence. When used as website navigation aids, the tags may be hyperlinked to items or objects associated with the tag. Tag clouds, however, are ineffective in capturing the changing nature of an object or objects within a website or webpage. FIG. 1 is an example of a prior art tag cloud 100 in which a group of users have tagged a webpage (not shown in FIG. 1). User A may tag an element or object in the website as “start”. User B may also tag the element or object in the website “start”. Accordingly, the tag “start” is depicted in the tag cloud 100 with a larger size or more prominently than other tags with a lower frequency of use or application to the webpage. As time passes, the nature of the webpage changes. However, the tag cloud remains the same. If a user C tags the element “STOP”, other viewers may not recognize the “STOP” tag as the more relevant or more important tag because of the weight or size of the “STOP” tag relative to the “start” tag. Thus, there is a need to manage tags within a tag cloud as conditions or the webpage changes.

BRIEF SUMMARY

DETAILED DESCRIPTION

The present invention may be a system, a method, and/or a computer program product. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention.

The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disc (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission medium (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire.

Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.

Computer readable program instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Java, Smalltalk, C++ or the like, and conventional procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize electronic circuitry, in order to perform aspects of the present invention.

Aspects of the present invention are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions.

These computer readable program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks.

The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks.

FIGS. 2A and 2B are a flow chart of an example of a method 200 for managing tags in a tag cloud in accordance with an embodiment of the present invention. In block 202, a tag for an object or associated with an object may be received. Examples of an object may include, but are not necessarily limited to, any content on a webpage, such as a news article, an image, a multimedia presentation or other content. A multiplicity of tags may be received over time that may be used to form a tag cloud associated with the object.

In block 204, each tag may be stored in a tag lookup table. Referring also to FIG. 3, FIG. 3 is an example of a tag lookup table 300 in accordance with an embodiment of the present invention. The tag lookup table 300 may include a “TAG” column 302 for storing an actual tag in each row 304 a-304 f; an “ID ASSOCIATED OBJECT” column 306 for storing an identification of the object associated with the tag; a “COUNT” column 308 for storing a count or a number of times the tag associated with the row 304 a-304 f has been applied to the object; and an “OVERLAY” column 310 for storing a link or pointer to another tag similar to that described in more detail herein. The tags may be stored in the TAG column 302 either case insensitive (without regard to any particular capitalization), or may be stored with an explicit case or capitalization that may be the same as that actually applied to the object and presented in the tag cloud. In the exemplary tag lookup table 300 in FIG. 3, the tags are stored in the explicit case as that applied to the object and as represented in the exemplary tag clouds 500 a and 500 b in FIGS. 5A and 5B which correspond to the exemplary tag lookup table 300. The tags may also be single words or multiple words.

In block 204, a tag history table may be provided for storing a tag creation date and an identification of the creator of the tag. FIG. 4 is an example of a tag history table 400 in accordance with an embodiment of the present invention. The tag history table 400 may include a “TAG” column 402 for storing the actual tag in each row 404 a-404 f; a “TAG CREATION DATE” column 406 to store a creation date of the corresponding tag; a “TAG CREATOR ID” column 408 to store an identification of the creator of the corresponding tag. The tag history table 400 may additionally include an “OTHER CHARACTERISTIC” column 410 that may be used to store some other characteristic associated with the corresponding tag that may be usable in determining if there is a relationship between a new tag, that is received by the system, and any of the existing tags stored in the tag lookup table.

In accordance with an embodiment of the invention, the tag lookup table 300 and the tag history table 400 may be combined in a single tag lookup table.

Referring back to FIG. 2A, in block 206, each new tag that is received may be compared to the existing tags that were previously received and stored in the tag lookup table. The new tag may be compared to the existing tags by using natural language processing (NLP) or a similar algorithm for comparing text. Comparing the new tag to the existing tags may also include determining if there is any relationship between the new tag and any of the existing tags. For example, the new tag may be compared to the existing tags to determine if the new tag is identical to any of the existing tags; the new tag is similar to any of the existing tags; the new tag is synonymous to any of the existing tags; the new tag is an antonym to any of the existing tags; or any other relationship or correspondence that may exist between the new tag and any of the existing tags. Determining other relationships that may exist between the new tag and any of the existing tags may be performed in block 222 as described below. Blocks 210-228 may be considered part of the comparing procedure. A tag relationship database 208 may be used to determine any relationships between the new tag and any of the existing tags.

The new tag may be compared to the existing tags in a predetermined sequential order. For example, the new tag may be compared to the existing tags starting with the most recently stored tag and progressing to the longest stored tag or from the longest stored tag to the most recently stored tag. The new tag may be compared to the existing tags alphabetically or in any combination of ordering from the tags being most likely related to least likely being related based on a mapping which may be defined by a user or users, defined by tag history, statistical analysis or any other mechanism for determining whether the new tag is related to the existing tags.

In block 210, a count associated with the tag may be incremented in the tag lookup table in response to the new tag being the same or corresponding to one of the existing tags. The count may correspond to the number of times the particular tag has been applied to the object or associated with the object by users. A tag weight or size may also be incremented or increased in the tag cloud corresponding to the count.

In block 212, a determination may be made if the new tag is an overlay tag. Similar to that previously described if the new tag is an overlay tag the new tag is linked to another tag or includes a pointer to another tag. An overlay tag may be defined as a tag that has a relationship or relationship bond between two or more tags. For example, the tags “Notes Tutorial draft” and “Notes Tutorial final” include overlay tags “draft” and “final” for “Notes Tutorial”. If the new tag is not an overlay tag and there is no relationship between the new tag and any of the existing tags, the new tag is added or applied to the tag cloud in block 214 and stored in the tag lookup table for comparison with future new tags that are received.

If the new tag is an overlay tag in block 212, the method 200 may advance to block 216. In block 216, a determination may be made if the overlay tag is over a set time threshold. For example, is the tag intended to exist for only a selected period of time, i.e., one day, one week, one month, or some other selected time period. If the overlay tag is not set for a time threshold, the overlay tag may be applied or added to the tag cloud based on the overlay in block 218.

If the overlay tag is set for a particular time threshold, the method 200 may advance to block 220. In block 220, the overlay property may be reset to show both the overlay tag and the related existing tag in the tag cloud based on the time threshold or time period set for the tags to appear in the tag cloud. The overlay property or time threshold may also be stored in the overlay column 310 of the tag lookup table 300.

In block 222, a relationship between the tag and any of the existing tags may be determined. Relationships between the tag and any of the existing tags may be determined in various ways. A relationship between the tags may be determined by the system using a learning algorithm. Examples of learning algorithms that may be used may include, but is not necessarily limited to, the C4.5 algorithm and natural language parsers. Relationships between tags may be defined by users of the system. A time of application of an initial tag and a subsequently received tag for the object may imply a change of state. The relationship may also be defined by a context of entry when the tag is applied to the object. Similar to that previously described, a tag relationship database 208 may also be used to determine relationships between the tag and the existing tags. The tag relationship database 208 may be preloaded using a custom curated mapping. A custom curated mapping is a mapping that is managed (curated) and customized to map tag terms together. For example, two or more tags may be mapped together when there is some relationship between the two or more terms, such as a company may change the name or other identification associated with a product and the two names or identities may be mapped together in the tag relational database 208. Examples of related tags that may also be stored in the tag relationship database 208 may include, but is not necessarily limited to, “start-stop”, “beginner-intermediate-advanced”, “beginning-middle-end”, “start-finish”, “left-right”, “up-down”, and similar relationships. The relationships may be formed using antonyms and may be further optimized using synonyms. The relationships may be unidirectional, i.e., advancing in the same direction, bidirectional or multidirectional, i.e., proceeding in two or more directions, or looped, i.e., recurring, such as begin day, middle of day, end of day, where the end of day loops back to the beginning of day. The looped relationship may be applicable to any time frame or any process or procedure that is repeatable or repeats.

The relationships may be categorized. The categories may be applied to specific object identifications (IDs) or limited to specific objects. A category may apply to a related group of items or objects, such as for example a specific group of products or other items.

In block 224, a determination may be made if there is any relationship between the tag and the existing tags from block 222. If there is no relationship the tag is added or applied to the tag cloud in block 226.

If there is a relationship between the tag and one of the existing tags in block 224, the method 200 may advance to block 228. In block 228, the one tag of the existing tags is selected in response to the tag and the one tag being related tags.

In block 230, the related tags may be presented in the tag cloud. Examples of presenting the related tags in the tag cloud may include, but is not necessarily limited to, removing or modifying the previously existing tag, managing the weight or size of the tags, the related tags may be associated with one another in a predetermined arrangement (positioning side-by side or some other arrangement), combining the related tags into one tag, hiding the previous tag, presenting the related tags with a combined weight or some other arrangement for presenting the related tags in the tag cloud.

An example of presenting the related tags in the tag cloud by managing the weight or size of the related tags may include setting a weight or size of the new tag and modifying a weight or size of the previously existing tag to represent a respective state of the related tags relative to a predetermined condition. The predetermined condition may include, but is not necessarily limited to, a time duration between creation of the respective related tags, a change associated with the object, such as a change in content of the object, a change in importance of the object relative to one or more users, a change in existence of the object, or other change associated with the object or webpage containing the object.

FIG. 5A is an example of a tag cloud 500 a before applying tag management in accordance with an embodiment of the present invention, and FIG. 5B is an example of the tag cloud 500 b resulting from managing the tags in accordance with an embodiment of the present invention. The tag clouds 500 a and 500 b correspond to the exemplary tag lookup table 300 in FIG. 3 and tag history table 400 in FIG. 4. In the tag cloud 500 a, the tag “start” (row 304 a, TAG column 302 in FIG. 3) is applied to the object (Website 1) by Jane and added to the tag cloud 500 a on May 24, 2013 (row 404 a in FIG. 4) and has a count of 4 (row 304 a, COUNT column 308 in FIG. 3). Bill creates and applies the tag “STOP” to the object (Website 1) on Dec. 15, 2014 (row 404 f, TAG column 402 in FIG. 4). The “STOP” tag has a count of 1 (row 304 f, COUNT column 308 in FIG. 3). Accordingly, the weight of the tag “STOP” is much less that the tag “start” and is shown as being much smaller in tag cloud 500 a without the tag management of the present invention. Because of the reduced weight or size, users may not notice the “STOP” tag relative to other tags in the unmanaged tag cloud 500 a in FIG. 5A.

However, the “STOP” tag is later in time and most likely more pertinent to the users of the tag cloud 500 a. Therefore, in tag cloud 500 b resulting from managing the tags as described herein, the weight or size of the “STOP” tag may be set to be presented at a selected weight or size relative to the “start” tag because of the “STOP” tag's more recent time of creation and relative pertinence or importance. The weight or size of the “start” tag may be modified to represent the respective states of the two related tags based on the predetermined condition of the respective times of creation and relative importance of the related tags to users of the tag cloud.

The “start”, “middle” and “STOP” tags may also be determined to be related tags by using the method 200 and may be arranged proximate one another or side-by-side as shown in the exemplary tag cloud 500 b in FIG. 5B in which tag management in accordance with an embodiment of the present invention has been applied. Similarly, the tags “a tag”, “B TAG”, and “C tag” may also be determined to be related tags and may be arranged proximate one another as also shown in the tag cloud 500 b in FIG. 5B resulting from managing the tags as described herein. Accordingly, presenting the related tags by managing the tags as described herein may include setting a weight of the new tag and modifying the weight of the related existing tag to represent the respective states of the related tags relative to a predetermined condition. The predetermined condition may include, but is not necessarily limited to, a time duration between creation of the related tags, a change associated with the object, such as a change in content of the object, deletion of the object, change in pertinence or importance of the object to users (change in context), a change in a threshold value associated with the object (whether the value is predetermined or dynamically created or updated), or other changes associated with the object or website.
